TECHNER LTD Equipment We Repair — By Category
TECHNER LTD Product Lines We Repair
Our engineers are trained on the full TECHNER LTD product range. Below are the major product families we service.
Techner Industrial PSU Series
Switched-mode power supplies designed for 24V, 48V and dual-voltage industrial control systems. Common faults include capacitor failures, thermal stress, and voltage regulation drift after prolonged operation in high-temperature environments typical of Indian foundries and textile mills.
Techner PLC Controller Modules
Compact programmable controllers for machinery automation, process control, and discrete logic applications. Repair challenges include EEPROM corruption, input/output card failures, and communication interface degradation in high-EMI factory environments.
Techner Analog Signal Conditioning Cards
4-16 channel analog input/output modules for sensor integration and actuator control in process automation. Typically fail due to sensor signal noise, ground loop issues, and connector corrosion in humid Indian climates.
Techner Serial Communication Gateways
RS-485, Modbus RTU, and industrial Ethernet interface modules for legacy system integration. Common issues include baud rate mismatches, termination resistor failure, and protocol stack corruption requiring firmware restoration.
Techner Temperature & Process Control Cards
Thermocouple and RTD signal conditioning with PID controller firmware for furnace, oven, and reactor temperature management. Failures arise from thermocouple junction corrosion, reference junction calibration drift, and firmware timeout errors.
Techner Field I/O Relay & Opto-Isolated Modules
Discrete input/output modules with 24V relay outputs and optocoupled inputs for machinery control and safety interlocks. Wear patterns include relay contact pitting, optocoupler LED degradation, and power transistor thermal failure in continuous-duty applications.

Common TECHNER LTD Equipment Faults We Fix
Based on 30+ years of repair data, these are the most frequent failure modes we see in TECHNER LTD equipment arriving at our workshop.
- ✓Techner PSU output voltage sagging under load — Electrolytic capacitor aging and ESR increase in the output filter stage, combined with transformer core saturation in high-ambient temperature conditions (40-50°C common in Indian plants). Voltage regulation feedback network also degrades, causing feedback voltage errors above 5-8V.
- ✓Techner PLC TC-100/200 won't boot or shows E-EEPROM corruption — EEPROM memory degradation due to power transients, voltage spikes from relay switching, or incomplete firmware writes during field updates. Indian industrial sites with poor grounding infrastructure are particularly susceptible to this fault.
- ✓Analog signal conditioning cards showing ±50mV offset or scaling errors — Precision op-amp drift due to temperature extremes, reference voltage IC failure, and pcb track corrosion from humidity and process vapors (common in cotton mills and chemical plants). Input buffer amplifiers can also exhibit gain drift with age.
- ✓Techner serial gateway timeout errors or communication dropouts — Baud rate mismatches, incorrect RS-485 termination resistors, or firmware stack corruption causing watchdog timer resets. Modbus CRC checksum errors often indicate corrupted gateway firmware due to incomplete updates or power loss mid-flash.
- ✓Temperature control card shows runaway output or frozen setpoint — PID controller firmware timeout due to corrupted EEPROM parameter blocks, sensor shorted/open circuit detection failure, or integral term accumulation causing controller instability. Common in high-temperature furnace applications (800-1200°C steel mills) where feedback sensor fails suddenly.
- ✓Relay module output stuck ON or relay chatter causing equipment damage — Relay contact welding due to high inrush currents, output power transistor gate-oxide damage from voltage spikes, or mechanical relay solenoid coil failure. Contactor chatter indicates missing snubber diodes or flywheel protection components.

Frequently Asked Questions — TECHNER LTD Repairs
Do you repair Techner Ltd equipment anywhere in India?+
Yes. Synchronics repairs the full Techner Ltd product range — power supplies, PLC controllers, analog I/O cards, serial gateways, temperature control modules, and relay interfaces. We offer PAN India door pickup from Mumbai, Delhi, Pune, Chennai, Hyderabad, Ahmedabad, Bangalore, Kolkata, and all other cities. Repair facility is centralized in Vadodara, Gujarat. We maintain original Techner firmware archives and genuine spare parts in stock for fast turnaround.
My Techner TC-200 PLC shows EEPROM error - can you recover my program?+
Yes. Synchronics has specialized tools to extract and analyze corrupted Techner EEPROM data. If your original source code is available, we re-flash the memory. If not, we attempt data recovery from the corrupted EEPROM sectors using forensic techniques. In all cases, we stress-test the memory and power conditioning circuit to prevent recurrence. Turnaround is typically 5-7 working days including verification testing.
What warranty do you provide on Techner Ltd repairs?+
All Synchronics repairs carry a 12-month functional warranty covering parts and labor. For critical Techner modules like PSUs and temperature controllers, we offer optional 18-month extended warranty. Warranty covers workmanship defects, component failures from our repair work, and thermal stress conditions — but excludes customer-caused damage, improper installation, or EMI/surge damage from site wiring. We provide detailed repair reports, test certificates, and recommendations for preventive maintenance.
Can you calibrate Techner analog I/O cards to our process sensor range?+
Yes. Synchronics calibrates Techner analog signal conditioning cards using NIST-traceable precision current and voltage sources. We perform multi-point calibration across your specific sensor range (e.g., 0-5V, 4-20mA, thermocouple uV ranges). Calibration uncertainty is ±0.1% of full scale. We provide calibration certificates, offset/gain trim documentation, and detailed calibration procedures for your plant maintenance team. Custom calibration adds 2-3 days to standard repair turnaround.
Techner PSU capacitors failing repeatedly - what's causing this?+
Techner PSU capacitor failures in Indian industrial sites are typically caused by high ambient temperature (40-50°C), humidity, and poor site AC supply grounding. We solve this by: (1) replacing all electrolytic capacitors with higher temperature-rated industrial-grade units, (2) applying conformal coating to pcb, (3) adding site surge protection recommendations (surge suppressors at AC input, proper grounding of neutral). We also measure actual site conditions (voltage ripple, frequency stability) and advise on AC stabilizer installation if needed.
How do I send my TECHNER LTD unit for repair?+
Pack the unit securely and courier it to our Vadodara workshop. Include a note with the fault description and your contact details. We will log it into our system and WhatsApp you a job number within 24 hours of receipt. Doorstep pickup is available in Vadodara, Ahmedabad, Surat, Mumbai, and Pune.
What is the cost of repairing a TECHNER LTD drive or PLC?+
Repair cost depends on the model and the fault. We offer a free diagnosis — once we identify the fault, we provide a fixed quotation before proceeding. Typical repairs cost 20–40% of the new unit price. We will never repair without your approval.
What warranty do you provide on TECHNER LTD repairs?+
All repaired units carry a 6-month comprehensive warranty covering the same fault and related issues. If the fault recurs within the warranty period, we repair it free of cost.
Do you provide a no-fix, no-fee guarantee?+
Yes. If we cannot repair your TECHNER LTD unit after diagnosis, you pay only the diagnosis fee (₹500–₹1,500 depending on the product). The unit is returned to you at no additional charge.
